UNAS 4 Two Minute Review - SHOULD YOU BUY IT?
Why It Matters
The UNAS 4’s aggressive price and easy integration lower the barrier for small businesses to adopt network storage, while its technical limits signal that more demanding workloads will still need higher‑end NAS platforms.
Key Takeaways
- •UNAS 4 priced at $379 offers four HDD bays.
- •Includes two M.2 NVMe slots and native 2.5 GbE.
- •Low noise and power draw around 10‑12 W during operation.
- •Integrated UniFi software works offline without Ubiquiti services.
- •No expansion; drives fixed, M.2 slots limited to caching.
Summary
The video reviews Ubiquiti’s UNAS 4, a compact network‑attached storage appliance now on sale for $379. It packs four 3.5‑inch drive bays, two M.2 NVMe slots, and a built‑in 2.5 GbE port, positioning it as a low‑cost, turnkey solution for small‑office or home users.
At the hardware level the unit draws only about 10‑12 W and measures roughly 34‑35 dB, making it both power‑efficient and quiet. The ARM‑based CPU with 4 GB of fixed memory runs Ubiquiti’s Drive 4.0 OS, which presents a single‑pane‑of‑glass interface for provisioning and monitoring. The front‑mounted LCD and bottom‑mounted drive trays give it a distinctive, service‑friendly design.
The reviewer notes that the NAS can operate completely offline, bypassing any Ubiquiti cloud services, which appeals to privacy‑concerned users. However, the PoE‑only connectivity means power and data share a single cable with no fail‑over, and the M.2 slots are limited to cache, not additional storage. Expansion is impossible beyond the four internal bays, and the USB port offers only basic external storage.
For buyers seeking an inexpensive, quiet NAS that integrates smoothly with existing UniFi networks, the UNAS 4 is compelling. Yet enterprises or power users requiring redundancy, expandability, or higher performance may find the device’s ARM processor, fixed memory, and lack of secondary ports restrictive, prompting consideration of larger Ubiquiti models or competing solutions.
